Referring to the embodiment of the invention illustrated in Figures I to XII inclusive, it willV be seen that in one reduction to practice thereof I may provide a plurality of. upright side posts 10 and 1l. connected by a series of transverse brace beams 13. 141-, 15 and 16. It is apparent, however, that any other type vof supporting frame for the machine may be used. On such a frame, forniingasupport therefor, I have 'provided a plurality of main machine elements includingay grinding mechanism, a glass supporting vtable adapted `to receive and support,

' preferably a plurality of sheets of glass, and

supported on the table into proper position to be ground and be adjusted as the grinding continues, to thus produce a uniform width of glass for the several sheets inserted in the machine.

To this end there is shown in the embodiment of the invention illustrated in Figures I to XII, a plurality olf grinding discs 1T and 18, or dii'l'erent sizes, .located within an enclosing receptacle 20. The grindimr discs 17 and 18 are provided with verticaI driving shafts 21 and 22, and it has been found that the transverse beams 13 and 14 form suitable means for carrying bearings 23, 24, 25and 26 for operatively supporting these shafts 21 and 22 on the beams. `Each of these shafts may be provided with driving pulleys 27 and 28 to receive belts for driving same from a suitable source oi power, as will be apparent.

Located within the enclosing easing 2() is a flat table 30 carried and fixed on an upright vertical shaft 31. This shaft 3.1 extends downwardly through a suitable bearing 32 in the transverse beam 15 and through a corresponding bearing 32 carried by the lowermost transverse post 16. The shaft 31 is provided with a driving pulley 33 also adapted to be operated by a belt from a suitable source of power, and rotated in the opposite direction of the rotation of the grinding discs 17 and 1S. The table 30 is adapted to receive a container or box-like support for a plurality of sheets of glass, and this construction will now be described.

By reference to Figures III, VI and VII, it will be seen that one construction of glass holder 35 is in the form of a box shaped container provided with a` base 36, a plurality of side frames 37, a rear wall 37', and a detachable front side 37". The base 36 is provided on the front and sides thereof with downwardly extending flanges 38 for the purpose of properly guiding,r and supportingr the container on the table 3() against lateral movement, one of thc flanges 38 (fo-operating with the front edge of the table il() to limit the inward sliding movenn-.nt of. thc container onto the table 30. By reference to igure VII, it will be seen that the tablc 30 may be provided, it desired. with a plurality of recesses 40 within which may hc. located rollers' fil extending slight-ly ahovc, the top plane of the hase or table ISU. upon which the bottom 36 of the glass container is adapted to roll upon the .insertion and rc,- moval of the container from the tahlc. This construction is entirely optional, however, and may be omitted it desired.

If desired, the container 35 which carries and holds a plurality of glass sheets A therein, may be additionally locked in position on the table 30 by any suitable lock, such as that shown in Figure VIII. To this end there is provided in one of the depending dll', adapted to normally project the latch 42 through the flange 38 oit the container. 'lhe tabled() provided with a recess into which the plunger or latch 42 is adapted to spring and auto]natically lool* the tlmno'e 3S of the container Seto the table 30, wlien the, same is slid tranwersely thereof sulliH ciently to bring; `theiront :tlano'e 38 into contact with an edge ot the table `30. lt will thus be seen that the container' 35 with the glass sheets A therein is looked on the table so as to securely hold the saine :in position during` an operation ot the machine, which rnay include a rotation oit the table 30.

ln the enilbodiinent oil the invention illl ve, in or to raise and lower the lglass to and lfroni proper operative position relative to the grindin,l mechanism and adiust the saine as `portions o'l the glass are egroluio oil', l have chosen to nieve the glass support and maintain the grinding discs snitionary within the machine, the rei erse beine; shown in a ineditication. `lo this end l have provided a movable leveiI 45, pivoted at el@ to the post 1l, the other end of the lever being adjustable, there "being a suitable threaded nut i" on said lever7 the nut being' carried by a screw threaded rod 418. `This rod lil be provided adjaeentits upper end with a bevel gear 4:9 messing with a bevel Irear 30 ou the cud ot a tretnsvcrse shatt whieh is pro vided on the outermost end oulhe trent `iaoe olt the niachine with an operateur handle 52. lt willthus be seen that up-ou rota tion oit the wheel or handle i2 inone wrectlonor the other, the lever to 'will be raised or lowered and that, by `a proper manipulation oi" the wheel the ,el is plates may be adjusted as the grinding;ruberation proceeds to level up all the sheets on the support BY 1"--1`'l1,r t0 lli "re "if it will be seen that one type el lever lll comprises a plu ality oit plates secured together between thoirends and provided substantially midway thereoil i yh :t widened portion between whieh is lone l a traufwers/.i blootF fill, ha\Y1 ius` au opeui e therein lov resolving the table sui, shalt l/L es ole'm "lv appears from lzipgure ,l liooated ou top et the plato l'l' rhay he a besu'iueA support :"t' lortu l just beneath a shoulderli" bearings 2li/l and 3Q whifV-,h earry the shalt The shoulder and bearings 36 thus torni a support for the shalt, and the pulley may likewise be partially supported. thereby.

Means are provided in the machine 'tor supplying an abrasive fluid to the edges or portion ot the glass being ground, one suit able arrangement :tor such a construction iii-- cludini; atank 60, suitably located on the loor adjacent to one ot the posts 'll ol the machine, an upwardly extendinepi pc (il, a receptacle or receiving tank 62 elevated above the grinding iuecl'iairisin, and a suitable pipe or connection extending trom the bottoni ol' the tank 62 termihating` in a downwardly extending; end 64 located with in the enclosure 20 and adjacent a space between the grinding discs 17 and i8. rl`he bottom oil the enclosure is provided with an opening,` 65, surroiuidinDr which is a :flange (3G, adapted to torno means iter collecting1 the abrasive itluid which has been sumdied to the ,grinding surilaces within the enclosure 2), the base et the enclosur-e 2() having a plu rality ol: drain troughs 67 and G7', which enlpty into a receiving,` projection (-38 on a y downwardly inclined trough o8', whereby the abrasive Al'luid is returned into the re ceiviire` tanlr 60.

lit desired, a suitable nieans may be einployed :tor agitating the abrasive lluid con: tained in the tank 60, such as a plurality oit pipes T0, "il and 72, connected through valves to a comnfion source ot air pipe 73, :ler sujnilyh'ur air under pressure to the several pipes il), Tl and 72, to constai'itlv agrin tate and mix the abrasive nuiterial v-Jithiu the .,inhi G0, which may consist oit a mixture ol enlery dust and liquid.

Shiitable ineens for :torcinpr the liquid trein the tanti (it) through the pipe Gl and into the elevated receptacle G2 may be employed, aud preterably the saine may consist olf pneumatic means intermittently operated so as to deliver a certain amount ot the liquid `or alu'asive material. into the tank` (l2, as

the same runs out into the grinding chamber 20. A suitable inecl'ianisin `tor this purpose consists in providing,- a branch pipe 75 leading` :troni the common pipe F3 et lthe source ot air ululer pressure, hence pass 1,9; throuejh a valved eomieetioo 7G., und aurtiL lary pipe 'T7 to the bottom ol' the inlet pori-- tion oi' the upright pipe til which eoinileets the tenh (30 with the elevated reservoir (ft2. 'lo the pipe section 7G l have located a vffilve ,7d adapted to be interniitteutly og'ierated to turn on and out olli' the supply oit sir under pressure to the bottom oil the pipe 'lf his oluiiatiirrr mechanism is illustrated in uros X, Xl and XH, where it will be seen that the valve 7,78 is provided with au exten sion or stud shalt 179 on which is located a pulley 80, connected by a belt Sl to the power shaft 82 ttor the machine. lt will thus ico 'be seen that the valve78 is coiitinuonsl)V roentering the manifold 84 from the inlet or supply pipe 77. It Will be noted that the lower edge of the pipe 61 isprovided With cnt-out recessed portions 87 to provide projections 88 against which the valve 86 abuts, and that the Huid :trom the tank 60 may pass through the opening around the valve 8G, through thek recesses 87 and into the pipe 61. The valve construction described operates as a check valvein the pump ot' this character, andadapts itselit tothe intern'iittent action of the pumping means employed herein operative to raise pre-determined amounts of abrasive fluid 'from the tank 60 to the upper receiving receptacle G2, as the same is used by the grinding machine.

I A suitable Wheeled vehicle or carrier ltor supporting (during loading) and bring the glass container 35 up to and in transferring position in relation with the grinding machine Will now be described. Thus, aboX like frame structure `100 may be provided with Wheels 101 adapted to operate on suitable rails 102 which are laid up to themagitudinal I-beains 106 and 107, cach of which may be provided with rails 108 running along the upper surface of the I-beams, said rails being adapted to receive and support the y container 35 thereon, there being certain lon- CIK gitudinally extending recesses 108 located in the base of the container 35 made tor that purpose.y The I--beaius and 107 are coinnected adjacent one end thereof by a transverse connecting beam 110. in loading a plurality ot sheets of. glass in the cotnainer 35, it is desirable to maintain the same on an inclination sufficient to permit the glass'slieets tirst inserted to be snpported in an. inclined manner, avoiding the necessity of any means ij'orholding some of the ysame in position While the others are being loaded into the container. Moreover,

the platform, it inclined, facilitates sliding As suggested, Y

tlie container onto the table 30 of the griiiding machine. To this end l have provided means for elevating the tracks 108 by a suitable elevating mechanism which will now be described.l

As shown iniFigures XV, XVI and XVII, the transverse I beam 110 is provided centrally thereof with a pair of dependingr ears 111, each of the ears being provided with means to support a transverse stud 112 in which is carried centrally thereof a threaded fnut or hub 113. This nut 113 is threaded on the upright screw threaded shaftv 114, which is carried by the vehicle frame 100. The

y lower end of the shaft 114 is provided with a the container 35, to prevent the same from sliding longitudinally off the supporting rails. The arm 117 is provided With a down- Wardlyextending stem or pin 118 extending through a guide 119 carried by the transverse yI beam 110, and provided with a hooked end 120. Coiled around the stem 118 is a spring 121 adapted to bear aginst the arm 117 and against the guide 119, normally tending to maintain the rod 117 in elevated position. Connected to the hook is a suitable handle 122 pivoted at 128 to the depending;` ears 111 adapted upon an oper- 'ation to draw the stein 118 downwardly and carry 'with it the arm 117, releasing the same from latcliing engagement with the Harige 38 to permit the container 35 to be slid onto the table 30 of the grinding machine. The rod 117 automatically latches the container 35 on the carrier 100 when the same is returned thereon,

An operation of the machine will, it is believed, be readily understood from the toregoing, Where it will be seen that a load of glass sheets A packed in the container 35 one direction while the grinding discs 17 and 18 are rotated in the opposite direction, while the pumping mechanism supplies an abrasive lnid to the pipe 64, between the tivo discs and adjacent to the Surcaces or edges of the discs or sheets of glass A being nanterre ground, certain of the highest portions on the sheets are trround oil', the operator `turns the liamlle '59 o `cont/imially adjust the `table il() Lind bring; theseveral sheets nearer arrange-nient shown herein, While one dise ttor grinding the edges olf the glass nnirjht be used, yet by providing two discs, (each eccentric to the center oi the rotating support for the glass sheets) each may be made smaller and operate more elliciently than a large one. llloreover, it is unnecesnary to malte disc ill as larggeas disc ill", disc l? is overlapped `relative to the `center of the mass oll plates il, to avoid a space between the two discs from coming,- over said center which would leave an unground pon tion at the middle oi? the rotating; mass olf plates. `ly rotating,1 both the discs l? and i8 and table 30, and rotating the discs in opino` site direction to the rotation ott' the supportor table 3l), it Will be seen that much more rapid action is obtained in fgrinding the glass sheets, the operation beine,l concluded in considerably less time than Would. be required il.2 the discs onlyvvere rotated as the result et the sinn oil' thespeeds otrotation obtained.
